About Q4117: Hyalomatrix wound coverage product
Q4117 reports Hyalomatrix furnished for wound coverage, with units based on the product’s square-centimeter measure and a primary application procedure.
Q4117 identifies Hyalomatrix, a wound-covering matrix made with hyaluronic acid and a protective outer layer. Clinicians may use it as a temporary covering in the treatment of acute or chronic wounds, including burns and hard-to-heal ulcers. The product is furnished in settings where a clinician performs a skin-substitute application, such as an outpatient wound clinic or hospital department.
Report Q4117 only with the primary procedure, such as the applicable skin-substitute application service; it is an add-on code and is paid within that procedure’s global period. Select the product code that matches the material actually furnished, and report units using the product’s square-centimeter measure. Records should identify Hyalomatrix, the wound treated, the area and amount applied, and the related application procedure. CMS classifies Q4117 as technical-component-only; interpretation is represented by a separate code when separately reportable.

Does Q4117 include the clinician’s work to apply the matrix?
Q4117 identifies the Hyalomatrix product. Report the applicable application procedure separately when performed; the product code is paid within that primary procedure’s global period.
How are Q4117 units determined?
The code is measured per square centimeter. Document the area and amount of Hyalomatrix used and report units under the applicable product-coding instructions.
What documentation supports Q4117?
The record should identify Hyalomatrix as the product furnished, the treated wound, the area covered, the quantity used, and the related application procedure.
Does Q4117 have a professional or technical component?
CMS designates Q4117 as technical-component-only, with interpretation covered by a separate code. The product line should identify the Hyalomatrix furnished.
